21 — -Body very broadly rounded, minutely punctulate, the elytra very broadly ex- 

 planate at the sides, the edge not thickened, pale, spotted with black, the epi- 

 pleuroe very broad, continuing to the sutural angles, with a large deep impression 

 internally at about basal third ; presternum transversely convex along the median 

 line, not bicarinate ; metacoxal plates as in Cycloneda ; epistoma feebly emargin- 

 ate, with coriaceous margin, the sides strongly dentate ; antennne and eyes as in 

 Cydonia. Asia and East Indies. (Subtribe Synonych.e. ) * Synonycha 



Body oval, rather strongly convex, minutely punctulate ; epistoma obliquely denticulate 

 at the sides, the extreme margin subtruncate ; antennae and eyes as in Coccinella ; 

 pronotum ornamented nearly as in Anatis, the apex less deeply sinuate and the 

 apical angles less pronounced ; elytra pale, or ornamented with irregular or in- 

 terrupted dark vittse, the side margins very narrowly reflexed, with the edge 

 thickened, the epipleurae narrower and simple ; metacoxal plates as in Cycloneda ; 

 presternum feebly convex along the median line. (Subtribe Mysi.k. ) 



Neomysia 



Ad alia Muh. 



The type of this genus is the Coccinella bipunctata of Linne, which 

 is now distributed very widely over the world through commerce. 

 The species before me are as follows : — 



Elytra without transverse series of spots ; metacoxal plates rounded or parabolic ; 

 elytral punctures fine 2 



Elytra with transverse series of spots or transverse bands ; metacoxal plates frequently 

 somewhat angular postero-externally ; pronotum pale, with an M-shaped black 

 design and a submarginal black spot 3 



2 — Elytra red, each with a rounded or oval black spot at the centre of the disk ; pro- 

 notum with a broad M-shaped median black design, the broad pale margins im- 

 maculate ; metacoxal plates rounded, extending but slightly beyond the middle 

 of the segment. Length 3.8-5.2 mm.; width 2.9-3.9 mm. United States (ex- 

 cept Pacific Coast) bipunctata Linn. 



Elytra red throughout and immaculate, the reflexed lateral margins usually yellowish ; 

 pronotum with M-shaped design and a black point at the centre of the broad 

 yellow margin ; metacoxal plates rounded, extending nearly to apical fourth of 

 the segment. Length 3.2-4.3 mm.; width 2.3-3.2 mm. California. 



melanopleura Lee. 



Elytra black with fine yellow side margins, each with a large oblong yellow spot at the 

 humerus and another, smaller and rounded, at three-fifths and close to the suture ; 

 pronotum black with narrow apical and side margins pale ; metacoxal plates par- 

 abolic, extending nearly to apical third. Length 3.9-4. 6 mm. ; width 2.8-3.25 

 mm. Utah to California (Siskiyou Co. ) humeral is Say 



3 — Submarginal black spot of the pronotum rounded and isolated, or only connected 

 to the black design by a narrow isthmus 4 



Submarginal black spot broadly amalgamated with the central black design, forming a 

 parallel- sided lateral extension of the latter ; elytra reddish-yellow with black 

 bands 5
